Abstract (en)
[origin: EP2762459A1] The present invention aims to provide a cover glass for display devices, made of soda-lime glass, excellent in cutting easiness and reliability of surface strength. The cover glass for display devices of the present invention includes a chemically strengthened glass, and has a compressive stress layer having a depth of 6 to 15 µm. In the cover glass, a shape parameter determined in accordance with JIS R 1625 (1996) based on analysis of a facture stress of the cover glass measured by a coaxial double ring test is not less than 7, and strength of the cover glass when a cumulative fracture probability is 1% is not less than 450 MPa. The glass plate before the ion exchange is made of soda-lime glass.
